The Jack Black-starring (and Ozzy, Halford and Lemmy-featuring) video game Brutal Legend could be delayed after original publisher Activision filed suit. Activision is suing developer Double Fine, which hopes to release this October via Electronic Arts after Activision dropped the game last year. Variety reports:

Activision has filed a lawsuit against videogame developer Double Fine Prods. that may prevent Electronic Arts from releasing “Brutal Legend” in October.

The videogame publisher claims that Double Fine missed a key deadline for “Brutal Legend” last year during its development and then set up the game with rival EA when it needed $7 million more and an additional nine months to finish it.

But Activision said in a lawsuit filed in the Santa Monica Courthouse, that it had never relinquished the rights to the game, in which it had already invested $15 million to develop. It also wasn’t paid back any money Double Fine was given to produce the game.

Company will suffer “irreparable harm” and lose not only sales from the game but also revenue from downloadable content, in-game advertising, merchandise and other opportunities if the release isn’t stopped, Activision said in the filing.
